Second harmonic generation microscopy of electromechanical reshaping on corneal collagen.

Refractive errors remain a global health concern, as a large proportion of the world's population is myopic. Current ablative approaches are costly, not without risks, and not all patients are candidates for these procedures. Electromechanical reshaping (EMR) has been explored as a viable cost-effective modality to directly shape tissues, including cartilage. In this study, stromal collagen structure and fibril orientation was examined before and after EMR with second-harmonic generation microscopy (SHG), a nonlinear multiphoton imaging method that has previously been used to study native corneal collagen with high spatial resolution. EMR, using a milled metal contact lens and potentiostat, was performed on the corneas of five extracted rabbit globes. SHG was performed using a confocal microscopy system and all images underwent collagen fibril orientation analysis. The collagen SHG signal in controls is uniform and is similarly seen in samples treated with pulsed potential, while continuous EMR specimens have reduced, nonhomogeneous signal. Collagen fibril orientation in native tissue demonstrates a broad distribution with suggestion of another peak evolving, while with EMR treated eyes a bimodal characteristic becomes readily evident. Pulsed EMR may be a means to correct refractive errors, as when comparing its SHG signal to negative control, preservation of collagen structures with little to no damage is observed. From collagen fiber orientation analysis, it can be inferred that simple DC application alters the structure of collagen. Future studies will involve histological assessment of these layers and multi-modal imaging analysis of dosimetry.

Medicare volume and reimbursement trends in lingual and hyoid procedures for obstructive sleep apnea.

OBJECTIVES: This study aims to analyze utilization and reimbursement trends in lingual and hyoid surgery for obstructive sleep apnea (OSA). METHODS: Annual retrospective data on lingual and hyoid OSA surgeries was obtained from the 2000-2021 Medicare Part B National Summary Datafiles. Current Procedural Terminology (CPT) codes utilized included 21,685 (hyoid myotomy and suspension [HMS]), 41,512 (tongue base suspension [TBS]), 41,530 (radiofrequency ablation of the tongue [RFT]) and 42,870 (lingual tonsillectomy [LT]). RESULTS: The number of lingual and hyoid OSA surgeries rose 2777 % from 121 in 2000 to 3481 in 2015, before falling 82.9 % to 594 in 2021. Accordingly, Medicare payments rose 17,899 % from an inflation-adjusted $46,958 in 2000 to $8.45 million in 2015, before falling drastically to $341,011 in 2021. As the number of HMSs (2000: 91; 2015: 84; 2021: 165), TBS (2009: 48; 2015: 31; 2021: 16), and LTs (2000: 121; 2015: 261; 2021: 234) only experienced modest changes in utilization, this change was largely driven by RFT (2009: 340; 2015: 3105; 2021: 179). Average Medicare payments for RFT rose from $1110 in 2009 to $2994 in 2015, before falling drastically to $737 in 2021. CONCLUSION: Lingual and hyoid surgery for OSA has overall fallen in utilization among the Medicare population from 2000 to 2021. However, there was a brief spike in usage, peaking in 2015, driven by the adoption (and then quick dismissal) of RFT. The rise and fall in RFT use coincide with the rise and fall in reimbursement.

Conventional clinical signs and symptoms are poor predictors of postoperative cerebrospinal fluid leak: A single-centre cohort perspective.

BACKGROUND: Postoperative cerebrospinal fluid (CSF) leak remains a concerning complication of the endoscopic endonasal approach (EEA) for skull base pathology. Signs and symptoms suggesting CSF leak often trigger additional workup during the postoperative course. We systematically evaluate associations between subjectively reported clinical signs/symptoms noted during the immediate postoperative period and incidence of postoperative CSF leaks. METHODS: Retrospective chart review was conducted at a tertiary academic medical centre including 137 consecutive patients with intraoperative CSF leak during EEA with primary repair between July 2018 and August 2022. Postoperative CSF leak associations with clinical signs and symptoms were evaluated using positive (PPV) and negative predictive values (NPV), sensitivity, specificity and odds ratio (OR) via univariate logistic regression. RESULTS: Seventy-nine patients (57.7%) had high-flow leaks repaired and 5 (3.6%) developed CSF leaks postoperatively. Of reported symptoms, rhinorrhea was most common (n = 52, 38.0%; PPV [95% CI] = 7.6% [4.8%, 11.9%]), followed by severe headache (n = 47, 34.3%; 6.3% [3.1%, 12.5%]), dizziness (n = 43, 31.4%; 2.3% [0.4%, 12.1%]), salty or metallic taste (n = 20, 14.6%; 9.9% [3.3%, 25.8%]), and throat drainage (n = 10, 7.3%; 9.9% [1.7%, 41.4%]). Nausea or vomiting constituted the most reported sign concerning for CSF leak (n = 73, 53.3%; PPV [95% CI] = 4.1% [2.0%, 8.1%]). On univariate regression, no sign or symptom, including rhinorrhea (OR [95% CI] = 7.00 [0.76-64.44]), throat drainage (3.42 [0.35-33.86]), salty/metallic taste (4.22 [0.66-27.04]), severe headache (3.00 [0.48-18.62]), dizziness (0.54 [0.06-4.94]), fever (3.16 [0.50-19.99]), and nausea/vomiting (1.33 [0.22-8.21]), associated with postoperative CSF leak. CONCLUSIONS: A range of subjectively reported symptoms and signs failed to predict postoperative CSF leak. Further investigation is warranted to inform appropriate attention and response.

The rising cost of rhinologic medications.

BACKGROUND: The high prescription drug cost in the United States may negatively affect patient prognosis and treatment compliance. OBJECTIVE: To fill the knowledge gap and inform clinicians regarding rhinology medications price changes by evaluating trends in price changes of highly used nasal sprays and allergy medications. METHODS: The 2014-2020 Medicaid National Average Drug Acquisition Cost database was queried for drug pricing information for the following classes of medications: intranasal corticosteroids, oral antihistamines, antileukotrienes, intranasal antihistamines, and intranasal anticholinergics. Individual medications were identified by Food and Drug Administration-assigned National Drug Codes. Per unit, drug prices were analyzed for average annual prices, average annual percentage price changes, and inflation-adjusted annual and composite percentage price changes. RESULTS: Beclometasone (Beconase AQ, 56.7%, QNASL, 77.5%), flunisolide (Nasalide, -14.6%), budesonide (Rhinocort Aqua, -1.2%), fluticasone (Flonase, -6.8%, Xhance, 11.7%), mometasone (Nasonex, 38.2%), ciclesonide (Omnaris, 73.8%), combination azelastine and fluticasone (Dymista, 27.3%), loratadine (Claritin, -20.5%), montelukast (Singulair, 14.5%), azelastine (Astepro, 21.9%), olopatadine (Patanase, 27.3%), and ipratropium bromide (Atrovent, 56.6%) had an overall change in inflation-adjusted per unit cost between 2014 and 2020 (% change). Of 14 drugs evaluated, 10 had an increase in inflation-adjusted prices, for an average increase of 42.06% ± 22.27%; 4 of 14 drugs had a decrease in inflation-adjusted prices, for an average decrease of 10.78% ± 7.36%. CONCLUSION: The rising cost of highly used medications contributes to increased patient acquisition costs and may pose barriers of drug adherence to particularly vulnerable populations.

Clinical Productivity and Patient Complexity of Academic Rhinologists: An Analysis of Medicare Metrics.

INTRODUCTION: Current data regarding reimbursement trends in Medicare services and the complexity of patients treated as physicians' progress in their academic career are conflicting. In otolaryngology, there are no data examining these metrics. METHODS: Medicare services, reimbursement, and patient complexity risk scores (based on hierarchical condition category coding) of US rhinology fellowship-trained faculty were stratified and compared by rank and years in practice. RESULTS: A cohort of 209 rhinologists were included. Full professors were reimbursed more per service than assistant professors ($791.53 [$491.69-1052.46] vs. $590.34 [$429.91-853.07] p = 0.045) and had lower risk scores (1.37 [1.26-1.52] vs. 1.49 [1.29-1.68], p = 0.013). Full professors had similar risk scores to associate professors (1.47 [1.25-1.64], p = 0.14). Full professors ($791.53 [$491.69-1,052.46], p < 0.001), associate professors ($706.85 [$473.48-941.15], p < 0.001), and assistant professors ($590.34 [$429.91-853.07], p < 0.001) were all reimbursed more per service than non-ranked faculty ($326.08 [$223.37-482.36]). As a cohort, significant declines in risk scores occurred within the 10th-14th year of practice (p = 0.032) and after the 20th year (p = 0.038). Years in practice were inversely correlated with risk score (R = -0.358, p < 0.001). CONCLUSION: Full professors were reimbursed more per service and treated less comorbid Medicare patients than junior academic colleagues. Patient comorbidity was correlated negatively with years in practice, with significant drops in mid and late career. Rhinologists employed at academic institutions had greater total reimbursement and reimbursement per service than non-ranked faculty. LEVEL OF EVIDENCE: N/A Laryngoscope, 2024.

The impact of nasal packing on skull base reconstruction and quality-of-life outcomes following endoscopic skull base surgery.

KEY POINTS: Nasal packing type was not associated with postoperative cerebrospinal fluid leaks Nondissolvable packing conferred an increased risk for postoperative sinonasal infections Nasal packing type did not influence short- and long-term quality-of-life scores.

Mutational landscape and predictors of survival in head and neck mucosal melanoma.

KEY POINTS: Head and neck mucosal melanomas have a diverse mutational landscape with low mutational burden. A molecular subset (∼13%) has ROS1 mutations, which is an actionable driver mutation. ROS1-mutated patients have improved overall survival likely due to high mutational burden.

Neuroinflammation drives sex-dependent effects on pain and negative affect in a murine model of repeated mild traumatic brain injury.

ABSTRACT: The Center for Disease Control and Prevention estimates that 75% of reported cases of traumatic brain injury (TBI) are mild, where chronic pain and depression are 2 of the most common symptoms. In this study, we used a murine model of repeated mild TBI to characterize the associated pain hypersensitivity and affective-like behavior and to what extent microglial reactivity contributes to these behavioral phenotypes. Male and female C57BL/6J mice underwent sham or repeated mild traumatic brain injury (rmTBI) and were tested for up to 9 weeks postinjury, where an anti-inflammatory/neuroprotective drug (minocycline) was introduced at 5 weeks postinjury in the drinking water. Repeated mild traumatic brain injury mice developed cold nociceptive hypersensitivity and negative affective states, as well as increased locomotor activity and risk-taking behavior. Minocycline reversed negative affect and pain hypersensitivities in male but not female mice. Repeated mild traumatic brain injury also produced an increase in microglial and brain-derived neurotropic factor mRNA transcripts in limbic structures known to be involved in nociception and affect, but many of these changes were sex dependent. Finally, we show that the antiepileptic drug, gabapentin, produced negative reinforcement in male rmTBI mice that was prevented by minocycline treatment, whereas rmTBI female mice showed a place aversion to gabapentin. Collectively, pain hypersensitivity, increased tonic-aversive pain components, and negative affective states were evident in both male and female rmTBI mice, but suppression of microglial reactivity was only sufficient to reverse behavioral changes in male mice. Neuroinflammation in limbic structures seems to be a contributing factor in behavioral changes resulting from rmTBI.

Complications of Novel Radiofrequency Device Use in Rhinology: A MAUDE Analysis.

With the widespread adoption of intranasal radiofrequency (RF) devices, our objective was to report national adverse events (AEs) associated with their use. The Food and Drug Administration's Manufacturer and User Facility Device Experience was queried. A total of 24 device-related AEs were reported, 11 (45.8%) for Celon® (Olympus), 3 (12.5%) for Vivaer® (Aerin), 2 (8.3%) for Neuromark® (Neurent), and 8 (33.3%) for Rhinaer® (Aerin). Seven (63.6%) of the Celon®-related complications were related to tissue necrosis (largely user error-related), but 1 (9.1%) episode of pediatric ocular palsy was also reported. Vivaer® complications included synechiae formation, a mucosal perforation, and a case of empty nose syndrome. Of the posterior nasal nerve ablating devices, 9 of 10 AEs were epistaxes, of which 7 (77.8%) required operative intervention. Surgeons should exercise vigilance and tissue-appropriate device settings when utilizing RF devices. Epistaxis and tissue necrosis may occur, as well as more rare, but devastating, complications.

Severe unilateral refractory epistaxis arising from the septal branch of the anterior ethmoid artery.

KEY POINTS: The septal branch of the anterior ethmoid artery (sbAEA) is an underrecognized source of severe refractory epistaxis. Herein, we describe the presentation, predisposing factors, treatment strategies, and outcomes of a series of patients with this condition.

Medicaid Acceptance Varies by Physician Seniority and Specialty in California.

Given varied insurance acceptances and differing pay between insurances, our objective was to examine the number of California physicians enrolled in Medicare and Medicaid (Medi-Cal), stratified by specialty and graduation year. Medi-Cal and Medicare providers were extracted from publicly available databases (Centers for Medicare & Medicaid Services and California Health and Human Services) and were subsequently merged into one dataset using National Provider Identifier. From there, we stratified physicians by specialty and graduation year. We found that emergency medicine, radiology, pathology, anesthesiology, general surgery, and internal medicine had the highest percent of Medi-Cal-accepting physicians, whereas dermatology, psychiatry, physical medicine & rehabilitation, and plastic & reconstructive surgery physicians had the lowest. There also appears to be an inverse relationship between acceptance of Medi-Cal and earlier year of graduation (P < 0.05). This study demonstrated striking variability in Medi-Cal acceptance based upon physician years in practice and specialty. Older, experienced physicians, as well as physicians of certain specialties, are less likely to accept Medi-Cal.

How Variable are Patient Comorbidity Profiles Among Practicing Otolaryngologists?

OBJECTIVE: To determine whether certain groups of otolaryngologists (ORLs) are treating cohorts of patients with more comorbidities. STUDY DESIGN: Cross-sectional population-based analysis. SETTING: 2019 Medicare Provider Utilization and Payment Dataset. METHODS: Each ORL's average Medicare hierarchical condition category (HCC) risk score, a comorbidity index calculated from a patient's comorbidities, was collected. These were stratified and compared by various physician characteristics, including practice region and rurality, years in practice, gender, subspecialty, and setting (academic vs community). RESULTS: Among 8959 ORLs, the mean HCC risk score for Medicare patients was 1.35 ± 0.35. On univariate analysis, ORLs practicing in urban (compared to rural), ORLs in academic settings (compared to community), and early career ORLs all had a patient population with a higher HCC risk score (P < .001 for all). On multivariate analysis controlling for gender, rurality, graduation year, and region, rural setting was associated with decreased odds of having a high-risk patient population (odds ratio: 0.58 [95% confidence interval, CI: 0.48-0.71]; P < .001), while those more recently graduated has an increased risk (2000-2009: 1.41 [1.01-1.96], P = .046; 2010-2015: 2.30 [1.63-3.25], P < .001). In a separate subgroup analysis, subspecialty differences were seen and community setting was associated with decreased odds of having a high-risk patient population (0.36 [0.23-0.55]; P < .001). CONCLUSION: There is variability in patient comorbidity profiles among ORLs, with those in urban settings, those more recently graduated, and those in academic settings treating a group with more comorbidities. As the comorbidity burden may increase the cost of practice and complications, these findings may have important implications for health inequity.

Boomerang Modification of the Septal Extension Graft: Graft Design and Functional Outcomes.

Background: A "boomerang" graft is an end-to-end caudal septal extension graft (SEG) that conforms to the geometry of the anterior septal angle, and avoids septal overlap, unlike a side-to-side SEG. Objective: To compare breathing improvements in rhinoplasty patients receiving boomerang SEGs and patients receiving side-to-side SEGs. Methods: Retrospective cohort analysis of patients undergoing rhinoplasty with either end-to-end boomerang SEG or a side-to-side SEG. Functional outcomes were assessed through the Nasal Obstruction Symptom Evaluation (NOSE) survey. Results: The boomerang SEG cohort had a mean age of 34 years and were 68% female compared with 38 years and 67% female in the side-to-side SEG cohort (p > 0.05). The cohorts did not differ in the proportion of the lateral crural tensioning, spreader graft placement, or history of rhinoplasty. The boomerang cohort demonstrated a 67% reduction in NOSE scores compared with a 70% reduction among the side-to-side SEG cohort (p = 0.14). Men undergoing boomerang graft placement reported significantly less postoperative functional improvement than men undergoing placement of a side-to-side SEG (62% vs. 77%, p = 0.01). Conclusion: Use of a boomerang graft is not likely to negatively affect rhinoplasty functional outcomes when compared with a side-to-side SEG.

Long-range optical coherence tomography of pediatric airway during drug induced sleep endoscopy: A preliminary report.

OBJECTIVE: Drug induced sleep endoscopy (DISE) is often performed for pediatric obstructive sleep apnea (OSA) when initial diagnostic studies do not provide adequate information for therapy. However, DISE scoring is subjective and with limitations. This proof-of-concept study demonstrates the use of a novel long-range optical coherence tomography (LR-OCT) system during DISE of two pediatric patients. METHODS: LR-OCT was used to visualize the airway of pediatric patients during DISE. At the conclusion of DISE, the OCT probe was guided in the airway under endoscopic visual guidance, and cross-sectional images were acquired at the four VOTE locations. Data processing involved image resizing and alignment, followed by rendering of three-dimensional (3D) volumetric models of the airways. RESULTS: Two patients were included in this study. Patient one had 18.4%, 20.9%, 72.3%, and 97.3% maximal obstruction at velum, oropharynx, tongue base, and epiglottis, while patient two had 40.2%, 41.4%, 8.0%, and 17.5% maximal obstruction at these regions, respectively. Three-dimensional reconstructions of patients' airways were also constructed from the OCT images. CONCLUSION: This proof-of-concept study demonstrates the successful evaluation of pediatric airway during DISE using LR-OCT, which accurately identified sites and degrees of obstruction with respective 3D airway reconstruction.

Impact of Tissue Handling and Size Modification on Septal Chondrocyte Viability.

INTRODUCTION: The physical modification of cartilage grafts during rhinoplasty risks chondrocyte death at the margins where the tissue is cut. This study compares chondrocyte viability between diced, scaled, and pate samples in human models, and further computes percent chondrocyte viability as a function of sequential dicing size in a computational model. METHODS: Septal cartilage from 11 individuals was prepared as follows: diced (1 mm cubic), scaled (shaved to <1 mm thickness ~ translucent), pate (0.02 g of scraped cartilage surface), positive control (2 × 2 mm diced), and negative control (2 × 2 mm diced soaked in 70% EtOH). Viability analysis was performed using Live/Dead assay™ and confocal microscopy. Numerical simulation of cartilage dicing in 0.05 mm increments was performed using MATLAB assuming 250 chondrocytes/mm3 with each average chondrocyte size of 65 µm2. RESULTS: Chondrocyte viability was similar between 1 mm diced cartilage, scaled cartilage, and positive control samples (p > 0.05). Conversely, pate samples had significantly less viability compared to positive controls, diced samples, and scaled samples (all p < 0.01 after Bonferroni correction). Pate samples had similar chondrocyte viability compared to negative controls (p = 0.36). On computational modeling, cartilage viability decreased to 50% as the diced sample was cut from 1 mm edge length to 0.7-0.8 mm. Similarly, cartilage viability decreased to 26% at 0.55-0.65 mm, 11% at 0.4-0.5 mm, and <5% at <0.4 mm edge length. CONCLUSION: Modifying septal cartilage grafts into 1 mm diced or scaled samples maintains ideal chondrocyte viability whereas pate preparations result in significant chondrocyte death. According to computational analysis, chondrocyte viability sharply decreases as the cartilage is diced below 0.7-0.8 mm. LEVEL OF EVIDENCE: N/A Laryngoscope, 2024.

Temperature Profile Measurement From Radiofrequency Nasal Airway Reshaping Device.

OBJECTIVE: Nasal airway obstruction (NAO) is caused by various disorders including nasal valve collapse (NVC). A bipolar radiofrequency (RF) device (VivAer®, Aerin Medical, Sunnyvale, CA) has been used to treat NAO through RF heat generation to the upper lateral cartilage (ULC). The purpose of this study is to measure temperature elevations in nasal tissue, using infrared (IR) radiometry to map the spatial and temporal evolution of temperature. STUDY DESIGN: Experimental and computational. METHODS: Composite porcine nasal septum was harvested and sectioned (1 mm and 2 mm). The device was used to heat the cartilage in composite porcine septum. An IR camera (FLIR® ExaminIR, Teledyne, Wilsonville, OR) was used to image temperature on the back surface of the specimen. These data were incorporated into a heat transfer finite element model that also calculated tissue damage using Arrhenius rate process. RESULTS: IR temperature imaging showed peak back surface temperatures of 49.57°C and 42.21°C in 1 and 2 mm thick septums respectively. Temperature maps were generated demonstrating the temporal and spatial evolution of temperature. A finite element model generated temperature profiles with respect to time and depth. Rate process models using Arrhenius coefficients showed 30% chondrocyte death at 1 mm depth after 18 s of RF treatment. CONCLUSION: The use of this device creates a thermal profile that may result in thermal injury to cartilage. Computational modeling suggests chondrocyte death extending as deep as 1.4 mm below the treatment surface. Further studies should be performed to improve dosimetry and optimize the heating process to reduce potential injury. Laryngoscope, 134:1063-1070, 2024.

Tissue Sealant Impact on Skull Base Reconstruction Outcomes: A Systematic Review and Meta-Analysis.

OBJECTIVE: Despite significant advances in understanding of skull base reconstruction principles, the role of tissue sealants in modifying postoperative cerebrospinal fluid (CSF) leak outcomes remains controversial. We evaluate postoperative CSF leak incidence associated with tissue sealant use in skull base defect repair during endoscopic skull base surgery (ESBS). DATA SOURCES: Web of Science, PubMed/MEDLINE, Scopus, and Cochrane Library. REVIEW METHODS: Systematic review and meta-analysis of risk differences (RD). A search strategy identified original studies reporting CSF leakage following ESBS with disaggregation by tissue sealant use and/or type. RESULTS: 27 non-randomized studies (n = 2,403) were included for qualitative and meta-analysis. Reconstruction with a tissue sealant did not significantly reduce postoperative CSF leak risk compared with reconstruction without sealant (RD[95% CI] = 0.02[-0.01, 0.05]). Sub-analyses of dural sealant (-0.02[-0.11, 0.07]) and fibrin glue (0.00[-0.07, 0.07]) compared with no sealant were similarly unremarkable. Postoperative CSF leakage was not significantly modulated in further sub-analyses of DuraSeal (0.02[-0.02, 0.05]), Adherus (-0.03[-0.08, 0.03]), or Bioglue (-0.06[-0.23, 0.12]) versus no dural sealant use, or Tisseel/Tissucol versus fibrin glue nonuse (0.00[-0.05, 0.05]). No significant association was seen comparing dural sealant use versus fibrin glue use on pairwise (0.01[-0.03, 0.05]) or network meta-analysis (-0.01[-0.05, 0.04]). Limitations in source literature prevented sub-analyses stratified by leak characteristics, defect size and location, and accompanying reconstruction materials. CONCLUSION: Tissue sealant use did not appear to impact postoperative CSF leak incidence when compared with nonuse. Higher quality studies are warranted to thoroughly elucidate the clinical value of adjunct sealant use in endoscopic skull base reconstruction. LEVEL OF EVIDENCE: N/A Laryngoscope, 2024.

Second Harmonic Imaging of Nasal, Auricular, and Costal Cartilage.

OBJECTIVE: There is little knowledge about the histological organization of facial and costal cartilages in terms of matrix structure and cell morphology. Second harmonic generation (SHG) imaging is a nonlinear imaging technique that capitalizes on signal generation from highly ordered macromolecules such as collagen fibers. The purpose of this study was to use SHG microscopy to image collagen extracellular matrix (ECM) structure, chondrocyte size, and density of these cartilages. STUDY DESIGN: Experimental. METHODS: Surgical remnants of septal, lower lateral, rib, and auricular cartilages were collected following surgery, sectioned into 0.5-1 mm thick samples and fixed to facilitate batch process imaging. A Leica TCS SP8 MP Microscope and multiphoton laser were used to image the specimens. Images were analyzed for cell size, cell density, and collagen fiber directionality patterns using ImageJ. RESULTS: SHG images of septal specimens show mesh-like structure of the ECM. There appears to be a superficial layer, characterized by flattened lacunae and middle zone, marked by circular lacunae clusters, similar to what is observed in articular cartilage. The structure of the ECM depicts a visible orientation perpendicular to the surface of the perichondrium. Cell size and density analysis through ImageJ suggests variety across cartilage types. Directionality analysis indicates that the collagen in the ECM displays preferred direction. CONCLUSION: This study establishes clear extracellular models of facial and costal cartilages. Limitations include heterogeneous cartilage thickness due to processing difficulties. Further studies include automating the cutting process to increase uniformity of tissue thickness and increasing sample size to further validate results.

Factors Influencing Graduates of American Academy of Facial Plastic and Reconstructive Surgery Fellowships Career Choice of Academic or Private Practice: A 20-Year Review.

Background: Absence of published literature on facial plastic and reconstructive surgery (FPRS) fellows' pursuit of academic careers hampers informed decision making for those interested in the specialty, fellowship program directors, and leaders in the American Academy of Facial Plastic and Reconstructive Surgery. Objective: To examine career choices among FPRS fellows from 2000 to 2019 and identify factors linked to academic or private practice employment after fellowship. Methods: Data from 796 fellows were analyzed, including gender, medical school, residency program, fellowship program, fellowship year, and degrees, to categorize them based on academic or nonacademic career placement. Logistic regression analyses were conducted to explore the association between demographic factors and academic career placement. Results: Forty-three percent (n = 345) obtained academic positions, with significant associations found between academic placement and additional advanced degrees, completion of fellowship training in the northeast, and residency training at an institution offering FPRS fellowship. Conclusion: Although fellows in FPRS predominantly pursue private practice, the decision to pursue academia is influenced by complex and multifactorial factors among graduates in the field.

Racial and ethnic disparities in the presentation size and timing of pituitary adenomas resected via endoscopic endonasal approach.

KEY POINTS: In a single-center cohort of pituitary adenoma patients, non-White race independently predicted larger tumor size at initial presentation. Uninsured patients suffered a significantly higher rate of pituitary apoplexy at initial presentation. Geographically distant care appeared to present a greater barrier for non-White and Hispanic patients relative to their White and non-Hispanic counterparts.
